PATENT OFFICE 2 Claims.

This invention relates to steam and hot water radiators in which there is combined in effect an outside modernistic radiator enclosure which is enclosed on top, back, sides and front,

5 with openings near the top (which may be covered by an air filtering material) for the discharge of heated and filtered air, and openings at the bottom for admitting air .to the inner part of the radiator,.a water tank built in and part of the end sections for the purpose of humidifying the atmosphere of a room, and extended fins on the faces of the inner sections, interfitting with fins on the adjoining section, thereby increasing the heat units absorbed by, and the velocity of the air passing through the radiator. The top may also be formed with a dead air space, in which space or box an insulating material may be placed to keep said top fairly cool so that it may be used as-a shelf :for books, etc.

With my improved radiator a smaller unit can be used, with considerable saving in the cost, as it is equal to a much larger size of the present open type sectional radiator now in use. On

account of humidifying and moistening the atmosphere, and the increased heated flue surface between the sections, the air passing through is more rapidly heated and circulated than by coming in contact with the ordinary open sectional radiator.

My humidifying tank, being a part of the end sections, is surrounded on three sides by the heating elements and as there is an open space between the inner face of the tank and the face of the inner radiator section, the rising air currents passing through said space become charged with the heated moisture from the water in the tank and are discharged into the room through the open grilles in the top front of the radiator and through the vent holes in the upper part of the outer face of the tank, thereby adding a large amount of moisture to the air in the room.

The back of my radiator, being practically closed, eliminates the discoloration of the walls and draperies (as is now the case with the ordinary open sectional radiator) as the heated and moistened air from the radiator is rapidly discharged into the room through filtering material behind the open grilles in the top front of the radiator and as said filtered air is discharged at some distance from the wall. The said moistened and filtered air is more healthy to breath and does not absorb the body moisture from the skin of the occupants of the room.

My radiator is designed to obviate the necessity and expense of an extra metal cover or other enclosure, such as is now used to hide the present unsightly open style radiators, as it has practically a smooth, fiat facing and appears like a cabinet. One of' the humidifying water tank end sections can be dispensed with for small radiators, and 5 other sections substituted. The open grilles in the top front face of the radiator can be closed by dampers placed either in back or front of said grilles.

Referring to the drawing showing one form my 1 invention may assume,

Fig. '7 is a perspective view of one of the shutters for closing the radiator.

From the exterior, my radiator has much the 5 appearance of a cabinet, being closed at the ends, front, back and top, except for open grilles l at the bottom for the admission of the cool air near the fioor and similar grilles 2 near the top for the discharge of the heated air toward the front and away from the wall. The upper grilles are preferably covered with a filtering substance, such as cheese cloth 3, to filter out the dust before discharging the air into the room.

My radiator is preferably made up of cast iron 35 sections 4, 4', 5, 6, l, 8, 9 and 9', like the standard radiator, but at least one end section is of different construction from the intermediate sections. Fig. 2 is an internal view through the center of my radiator, showing sections connected together in somewhat similar manner to the ordinary steam and hot water radiators, either by screw or slip nipples 3|]. As shown, both end sections 4 and 9 are made in the form of a rectangular box having a main central section I!) adapted to con- 45 tain water at atmospheric pressure, and end compartments or pipes II and I2 communicating at the bottom with the live steam (or other heating fluid) channel l3 and also at the top with the steam channel M, if such is present. Between it 50 and the next section 4' there is a flue 40 for air to pass through. The water compartment has a slotted opening IS in the outer wall near the top, through which it may be filled and through which the evaporated moisture escapes, and a drain cock 55 IT at the bottom. A moisture discharge opening 2| may also be provided in the inner wall l so that the moisture laden air will be entrained by the heated air rising through said flue 40 and discharged through the end grille 2. Also the water tank may be filled from the front, if desired, by opening an end grille 2 and pouring the water in opening 2|. The passage 43 is closed on its inner side by the adjoining Wall of the next section 4', which is provided with a steam channel IS. The inner face 20 of the said section is preferably provided with a plurality of outwardly projecting radiating fins l8 cast or otherwise intimately united with the exterior wall thereof and placed in staggered relation to complementary fins IS on the adjacent face of the next section The inner sections each have a central steam chamber 22 provided with fins l9 and 23 on opposite sides thereof, which interfit with those on the adjacent sections, thus forming a plurality of parallel fines to increase the rate of air flow and heating.

At the top, the sections fit together to form a fiat top 25, preferably of double thickness to provide a dead air space 26, so that the top will remain comparatively cool so that it may be used as a shelf. If desired, insulating material 24 may be provided within said space, or small openings may be made therein.

I also may provide movable shutters 21, 28 for closing the grille openings at the top and bottom so that the radiator may be effectively shut off without closing the steam valve 29. It should be noted that I prefer to locate said valve underneath the radiator, so that it and the steam connections 31 and 38 are entirely enclosed within the outer casing. Doors 39 and 39' may be provided to gain access to the valve and fittings.

By my improved radiator I have made a simple, compact device which will humidify and purify the air as well as heat the same, and which can be manufactured according to standard practice in radiator construction, which is ornamental, and which, in spite of the fact that it is enclosed,

will heat a greater quantity of air than an ordinary radiator of similar overall dimensions.

It is of course obvious that the water containing sections need not be confined to the end sections. If desired, one or more intermediate sections may have water compartments, as indicated in Fig. 6. In this figure the steam sections are on the outside at 3| and 32. The central section 33 is adapted to be partially filled with water, and in the center thereof is shown a third steam riser 34. If desired, this unit may be built up of three sections, as shown. This figure also illustrates a different form of radiating ribs or fins. As shown on the left hand side, ribs 35 may be made in the form of saw teeth, which interfit with similar teeth 35 on the next section 36. Rapid heating of the air is obtained in this manner.

In accordance with the provisions of the patent statutes, I have herein described the principle and operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other means. use the various features and elements in the combination and relations described, some of these may be altered and others omitted without interfering with the more general results outlined, and the invention extends to such use.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. A sectional radiator of the box or enclosed type, comprising an end section having a channel for the heating fluid and an adjacent compartment for evaporating water which is heated by said fluid, an intermediate section having laterally projecting fins, said sections interfitting to completely enclose the interior thereof, except for openings adjacent the top and bottom for the exit and entrance of air.

2. A sectional radiator as claimed in claim 1, in which the top of each section is cast with a dead air space to keep the same cool.
